European Tech Stocks Rebound as Middle East Oil Supply Risks Persist
Taylor Wilson
The STOXX 600 rose 0.4% Thursday, led by a 1.6% tech-sector rally after reports that China may let domestic AI firms buy Nvidia H200 chips; yet oil-tanker flows through the Strait of Hormuz have dropped to roughly 70% of normal, keeping crude prices and geopolitical risk at the center of the market's attention.
Why did tech stocks suddenly lead the rally?
Chip names surged hardest: Germany's wafer maker Siltronic +7.4%, France's semiconductor-materials firm Soitec +5.5%, lithography giant ASML +2.5%.
The catalyst was a report that China may allow domestic AI companies limited access to Nvidia's H200 chips, lifting expectations for AI-infrastructure demand.
This means → tech just posted its strongest quarter since 2001, yet has been the worst-performing STOXX 600 sector this month. Thursday's move looks more like a short-term bounce off oversold levels than a trend reversal.
How is the Middle East situation rattling markets?
Trump announced Wednesday that the interim peace deal with Iran is over, revoked waivers allowing Iranian oil sales, and launched a fresh round of strikes.
The STOXX 600 posted its biggest single-day drop since March in response.
Trump also said Iran wants to "make a deal," leaving room for interpretation. Crude prices edged lower Thursday. In plain terms = one hand strikes, the other negotiates — and the market is forced to price both scripts at once.
How far have Hormuz oil flows fallen?
Goldman Sachs estimates Persian Gulf crude output in June was still about 10.5 million barrels per day below pre-war levels. After recent tanker attacks, strait flows fell from above 80% of normal in the first ten days after reopening to roughly 70%.
Goldman analyst Yulia Zhetkova Grigsby noted: "Transit risks remain elevated; shippers may hesitate to cross the strait." After two consecutive days of mutual US–Iran strikes, vessel traffic through the strait nearly ground to a halt.
This means → Brent crude briefly topped $80 a barrel this week — not because demand pulled it there, but because the supply corridor is being squeezed and the market is pricing in that choke-point risk.
What determines the next move in oil prices?
Goldman offers two paths: if a 60-day negotiation advances and Iranian oil waivers are restored, strait flows could normalize by end of July; if talks collapse and attacks escalate, flows could fall further.
In plain terms = oil is trading on a "negotiation premium" right now — a deal brings it down, a breakdown pushes it up, and the direction hinges on whether Hormuz talks restart.
This reflects a core tension: tech stocks want to rally on the AI narrative, but geopolitical risk can wipe out a day's gains in a single headline.
What signals are coming from individual stocks and regional markets?
AstraZeneca fell 8% after Wainua — a neurological drug developed with US-based Ionis — failed to meet its primary endpoint in a late-stage trial (reducing cardiovascular death and recurrent cardiac events).
Spain's IBEX rose 0.9%, outperforming the rest of Europe, after Trump called Spain "very generous" on NATO contributions, lifting sentiment.
This means → on the same day, geopolitical remarks both crushed (Iran) and boosted (Spain) equity markets — a sign that European stocks are far more sensitive to political signals than to fundamentals right now.
